Entangled edge states of corank one with positive partial transposes
Jinwon Choi, Young-Hoon Kiem, Seung-Hyeok Kye
We construct a parameterized family of PPT (positive partial transpose) states of corank one for each . With a suitable choice of parameters, we show that they…
Log BPS numbers of log Calabi-Yau surfaces
Jinwon Choi, Michel van Garrel, Sheldon Katz +1
Let be a log Calabi-Yau surface pair with a smooth divisor. We define new conjecturally integer-valued counts of -curves in . These log BPS numbers…
Local BPS Invariants: Enumerative Aspects and Wall-Crossing
Jinwon Choi, Michel van Garrel, Sheldon Katz +1
We study the BPS invariants for local del Pezzo surfaces, which can be obtained as the signed Euler characteristic of the moduli spaces of stable one-dimensional sheaves on the sur…
The refined BPS index from stable pair invariants
Jinwon Choi, Sheldon Katz, Albrecht Klemm
A refinement of the stable pair invariants of Pandharipande and Thomas for non-compact Calabi-Yau spaces is introduced based on a virtual Bialynicki-Birula decomposition with respe…
